Question

Q1) using appropriate properties find : -2/3 X 3/5 +5/2-3/5X1/6 .
Q2) find ten rational numbers between 3/5 and ¾.​

Answer 1

Step-by-step explanation:

q1. -2/3 ×3/5 + 5/2- 3/5× 1/6

now applying BODMAS rule

so

-6/15 + 5/2 - 3/30

5/2-(6/15+3/30)

5/2-((12+3)/30)

5/2-15/30

(75-15)/30

50/30

or

25/15

Q2.

3/5

multiply numerator and denominator by 12

now 3/5 ×12= 36/60

3/4

multiply numerator and denominator by 15

3/4×15= 45/60

now 10 rational no are

37/60,38/60,39/60,40/60,41/60,42/60,43/60,44/60,45/60
